I don't know what to say to that, except John 5:46.
Then see it in the entirety:
John 5:
36
But I have greater witness than that of John: for the works which the
Father hath given me to finish, the same works that I do, bear witness of me, that the Father hath sent me.
37
And the Father himself, which hath sent me, hath borne witness of me.
Ye have neither heard his voice at any time, nor seen his shape.
38 And ye have not his word abiding in you: for whom he hath sent, him ye believe not.
39 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
40 And ye will not come to me, that ye might have life.
41 I receive not honour from men.
42 But I know you, that ye have not the love of God in you.
43 I am come in my Father's name, and ye receive me not: if another shall come in his own name, him ye will receive.
44 How can ye believe, which receive honour one of another, and seek not the honour that cometh from God only?
45 Do not think that I will accuse you to the Father:
there is one that accuseth you, even Moses, in whom ye trust.
46 For had ye believed Moses, ye would have believed me; for he wrote of me.
47 But if ye believe not his writings, how shall ye believe my words?
Moses wasn't truth. He gave a Law for flesh. Christ fulfilled the Law through love that the Holy Spirit provided. No Jew had ever had this.
John 1:
12 But as many as received him, to them
gave he power to become the sons of God, even to them that believe on his name:
13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
15 John bare witness of him, and cried, saying, This was he of whom I spake, He that cometh after me is preferred before me: for he was before me.
16 And of his fulness have all we received, and grace for grace.
17 For the law was given by Moses, but
grace and truth came by Jesus Christ.
18 No man hath seen God at any time, the only begotten Son, which is in the bosom of the Father, he hath declared him.
Moses was never the truth. He started a path that Jesus as Christ ended. John 5:36 says Jesus came to finish what had started. And he did so with the words "It is finished". Once risen, he gave the Holy Ghost that had guided him as Christ to those whom he saw after he arose (Paul says more than 500). But he clearly gave the Spirit (mother) to the disciples John 20:22
He couldn't give it until he taught who it was and how to use it. John 7:39
The OT was closed (finished) and the gnosis of the Spirit began by those who had received it. The catholics have divided the early Christian books to appease the OT Pharisee's. They teach the Bible instead of the Gospel.
Galatians Chapter 1 and 2 speaks of Pauls struggle with this "new" gospel based on the Jews religion.
Which is why I left orthodoxy decades ago, for spiritual gnosis from the Spirit.
